There are no numbers without decimals which multiply to 78 and add up to 17.
Answer:
Solution is given by (-2,-1)
Step-by-step explanation:
2x-3y = -1
11x-9y = -13
Multiplying equation 1 by -3 and adding it to equation 2 ,we get
-6x+9y = 3
11x -9y = -13
___________
5x = -10
gives x = -2
plugging this value in equation (1) ,we get
2(-2) -3y = -1
-4 -3y =-1
-3y =-1+4
-3y =3
y = -1
solution is (-2,-1)
